Default template

[Stewbond]

We can set a default type for a template class like so:

template <class T = double>
class someClass
{
    T m_member;
};

The above compiles only if I declare my object like so:

someClass<> someObj;
someClass<bool> someOtherObj;

Is there a way to define my class so that the objects can be created like so?

someClass someObj;
someClass<bool> someOtherObj;

My colleagues are all aerospace/mechanical/electrical engineers, so I can't make any classes that are too complex to use. I want it powerful for advanced users, but need it simple for people that write C++ as if it was C).
